Lindy's WhatsApp Integration: Initiating Business Conversations Guide

Hi all, Does anyone have experience with Lindy’s Whatsapp integration? Specifically how to initiate business conversations and send Whatsapp template messages? I’ve got the basic integration set up but would like to have a workflow that can initiate some conversation, can’t seem to figure out if the integration can do this or I need to use another 3rd party tool like wati.io
